Product Description
The Yokogawa SB401-10 is an ESB Bus Interface Slave Module used within the Field I/O (FIO) system architecture of Yokogawa’s CENTUM VP platform. It functions as a communication interface between the Field Control Unit (FCU) and the I/O modules through the ESB bus. It supports high-speed data transfer and reliable operation in both single and dual-redundant configurations. As part of the ESB Bus Node Unit (model ANB10S or ANB10D), the SB401 ensures efficient power and signal communication for analog and digital I/O modules.
